Remote Management Feature
Server management is concentrated in the Remote Management Controller (RMC). The RMC and associated circuitry are
powered from a 5Vdc standby voltage, which remains active when system power is switched off, but the ac power source is
still on and connected.
The RMC supports the NEC ESMPRO Manager, which allows remote server management through networks. Events
monitored by the manager system include over-temperature and over-voltage conditions, fan failure, or chassis intrusion.
Information on NEC ESMPRO Manager may be found in the ExpressBuilder DVD.
One major function of the RMC is to autonomously monitor system management events, and log their occurrence in the
nonvolatile System Event Log (SEL). The events being monitored include over temperature and overvoltage conditions, fan
failure, or chassis intrusion. To enable accurate monitoring, the RMC maintains the nonvolatile Sensor Data Records (SDRs),
from which sensor information can be retrieved. The RMC provides an ISA host interface to SCR sensor information, so that
software running on the server can poll and retrieve the server's current status.
The RMC performs the following:
 Monitors server board temperature and voltage*
 Monitors processor presence and controls Fault Resilient Boot (FRB)
 Detects and indicates baseboard fan failure*
 Manages the SEL interface
 Manages the SDR Repository interface
 Monitors the SDR/SEL timestamp clock
 Monitors the system management watchdog timer
 Monitors the periodic SMI timer
 Monitors the event receiver
 Controls secure mode, including video blanking, diskette write-protect monitoring, and front panel lock/unlock
initiation
 Controls Wake On LAN via Magic Packet support.
 Monitors the hard disk drives
 Verifies system configuration data (CPU, memory, and others)
*Also, NEC ESMPRO supports these features.
